SPECIFICATION formingpart of Letters-Patent No. 278,698,7dated June 5, 1883.

Application filed January 22, 1883.

To all whom it may concern:

Be it known that we, JAMES GARLAND and JAMES KENYON, of Lynchburg, in the county of Campbell and State of Virginia, have invented certain Improvements in CarAxle Boxes, of which the following is a specification.

The object of our invention is to provide an axle-box for railroad-cars which shall secure the thorough lubrication of the axle under all conditions and relieve the same from excessive friction and strain in the event of the car being overloaded. XVe therefore construct a box or housing the lower portion of which serves as an oil-reservoir. In the upper por tion of this box we secure a removable bearing-plate, in which the axle rests. Ve pro# vide a ring encircling and resting upon-'the axle, and bearing at its lower edge in the oil, for the purpose of feeding the latter to the journal. To prevent the oil from working outward around the axle, we provide a peculiar arrangement of yielding packingplates- For the purpose of returning the oil from the journal to the lower portion or reservoir, and of preventing it from being thrown out of the latfer by the violent motion to which the box is subjected by the motion of the car, we provide shields or deflect-ors in the lower part of the box. To provide a special means of lubrication in the event ofthe axle becoming heated, we provide a removable perforated receptacle to contain tallow Vor other solid lubricants, which remain in an unchanged condition so long as the axle runs without becoming heated. For the purpose of equalizing and relieving the strains upon the journal and spring, we connect the vertically-movable j ournal-box with the car-truck by levers and rods or equivalent devices, through which the weight of the car-body or a portion of the same may be applied to the under side of the axle-box.

Referring to the accompanying drawings,

Figure l represents a vertical section through the center of our box in line with the axis of the journal. Fig. 2 is a vertical cross-section ofthe same on the line x x'. Fig. 3 is a crosssection of the same on the line y y. Fig. 4 is a perspective view of the receptacle for tallow or other solid lubricant. Fig. 5 is a view of the lining or journal-bearing proper removed.

box or casing, designed to serve as an oil-receptacle and contain the other parts of the bearing. It may be made of any ordinary or suitable form externally. It has on opposite sides the usual anges or lips to secure it in the hanger or bracket B ofthe car-truck, in which Vit is arranged to slide vertically, as usual. 'A spring, C, interposed between the upper side of the box and the truck, serves as an elastic support for the former. In place of the spring shown, any other spring or combilhe body A is perforated on its under side to admit the end of the axle D, which is made of the ordinary form, with a reduced journal or neck at shown in Fig. 5, with a rib or projection on its upper side seated and secured by a pin in a suitable recess in the upper side of the body. At its middle the bearing E is provided with a transverse groove, c, to admit a large ring, F, which is suspended loosely around and upon the axle within said groove, so as to be revolved by the motion of the axle. This ring is made of greater diameter than the axle, and hangs downward within the lower portion of the body, its lower portion being immersed in the oil contained therein, the ring being thus caused vto feed a continuous supply of oil to the upper surface of the journal when the latter is in motion. The lower portion of the body A is made in the form of a tight cup or reservoir to contain the body of oil, and is provided with a screw, b, through which the implnire oil may be withdrawn at will.

' To prevent the oil from being thrown out of the box accidentally, we provide the body A with two plates or shields, c, extending. inwardly from .its opposite sides immediately below the axle, suicient space being left between their inner edges for the passage of the ring which hangs between them. As shown in the drawings; these plates or guards have a downward inclination, in order that any oil delivered upon `their upper surfaces will flow IOOl - ofthe box, and in this respect they are superior to plates the outer edges of which terminate at/ points within the box or reservoir. As a further means of preventing the escape of oil from the box around the axle, we form in the inner end of the body a vertical chamber surrounding the axle, and insert therein through its upper end on each side a sheet of felt, leather, or equivalent packing material, e, and against the inner surface of each of these sheets we place a metal plate to retain the same in position. Between the two plates F we insert, above and below the axle, verticallysliding packing-plates g, notched at their adjacent edges to t closely around the axle. Springs h, applied above andV below the plates g, hold the same in close contact with the axle. For the purpose of permitting the introduction and removal of this packing an opening` is made in the top of the body A, and closed by means of a removable slide, 1', as shown in Fig. l.

For the purpose of providing lubricating material which shall be brought automatically into use in the event of the box becoming heated,we provide in the top of the body above the space occupied by the bearing-plate E a horizontal chamber. XVe next provide a thin metallic receptacle. (Shown at H, Figs. l and 4L.) As shown, this receptacle consists of a horizontal tray perforated in the bottom, and provided at one end (with a downwardly extending chamber or pocket, 7c, which is also perforated on the inner side. This entire receptacle being charged with tallow or other suitable lubricating material or compound, which will remain solid and immovable at ordinary tem perature, is applied as shown in Fig. l, its horizontal portion being thrust into the chamber in the top of the body, and its portion being permitted to extend downward opposite the end of the journal, as shown. These portions of the body lying beneath the tray and the bearing-plate E are both provided with vertical perforations extending downward above the journal and axle, as shown.

During the ordinary action of the box, and while it is properly supplied with oil, the solid lubricating material remains unchanged and inactive; but in the event of the parts becoming heated from any cause the heat will be transmitted through the intermediate metal to the tray H, in consequence of which the tallow will be melted and caused to pass downward upon and around the j ournal and its bearing-plate, effecting a thorough lubrication of the wearing-surfaces. The employment of a solid lubricating material which remains ordinarily in an inactive condition is important in that it constitutes an auxiliary or supplemental means of lubrication, which, although underv ordinary circumstances of no effect, will be brought into action in the case of an emergency, as when the ordinary lubricant becomes exhausted, or from other reasons the box becomes overheated. The outer side of the body is closed and the tray H retained in position by sides of the body A. To the outer ends of these levers we connect vertical rods or arms K, extending upward, and arranged at their upper ends in'suitable position to be acted upon by the body of the car, or a bolster or other device upon the body in the event of the body being depressed below its ordinary position. These rods may be constructed in any suitable form and guided by ears or bearings in the sides of the bracket B, or inany other suitable manner. Vhen thus depressed the weight of the body will be transmitted through the rods and levers and applied in a measure to the under side of the box, the weight of which is thus carried partially bv the levers I. The present invention is restricted to those matters and things which are hereinafter claimed, and as to all matters which may be described or shown, but which are not claimed, the right is reserved to make the same the subject of a separate patent.

Having thus described our invention, what we claim is 1'. In a car-axle box, the combination of th axle, the body'A, the packing-plates c and f, encircling the axle, the intermediate plates g, and the springs H, acting upon said plates.

'2. In combination with the axle, .the body A, having an oil reservoir or chamber in its base, the bearing E, the feed-ring F, and a supplemental tray, H, in communication with the journal by openings or perfor-ations, substantially as described.

3. In combination with the axle, the oil-containing body and bearing E, the pendent ring F, and the guard-plates c, joined closely to the outer ends of the body A and extending thence inward toward thering.

4. In combination with the body, the axle, and the axle-bearing, the trayl H, provided with the horizontal and depending perforated portions, substantially as described.

5. The car-body, in combination with the car-truck, the axle, the vertical sliding axlebox, the spring, and means, substantially as described, connecting the car-body with the axle-box, tending to elevate the latter, substantially as described and shown.

6. In combination with'the car-truck, the vertical sliding axle-box, levers I, and rods K, substantially as shown.
